Announcing our updated Responsible Scaling Policy

Today we are publishing a significant update to our Responsible Scaling Policy (RSP), the risk governance framework we use to mitigate potential catastrophic risks from frontier AI systems. This update introduces a more flexible and nuanced approach to assessing and managing AI risks while maintaining our commitment not to train or deploy models unless we have implemented adequate safeguards. Key improvements include new capability thresholds to indicate when we will upgrade our safeguards, refined processes for evaluating model capabilities and the adequacy of our safeguards (inspired by safety case methodologies), and new measures for internal governance and external input. By learning from our implementation experiences and drawing on risk management practices used in other high-consequence industries, we aim to better prepare for the rapid pace of AI advancement.

Introducing Claude Opus 4.5

Our newest model, Claude Opus 4.5, is available today. It’s intelligent, efficient, and the best model in the world for coding, agents, and computer use. It’s also meaningfully better at everyday tasks like deep research and working with slides and spreadsheets. Opus 4.5 is a step forward in what AI systems can do, and a preview of larger changes to how work gets done.

Accenture and Anthropic launch multi-year partnership to move enterprises from AI pilots to production

Anthropic acquires Bun as Claude Code reaches $1B milestone

Claude is the world’s smartest and most capable AI model for developers, startups, and enterprises. Claude Code represents a new era of agentic coding, fundamentally changing how teams build software. In November, Claude Code achieved a significant milestone: just six months after becoming available to the public, it reached $1 billion in run-rate revenue. And today we’re announcing that Anthropic is acquiring Bun—a breakthrough JavaScript runtime—to further accelerate Claude Code.

Introducing Claude Haiku 4.5

Claude Haiku 4.5, our latest small model, is available today to all users.

Thoughts on America’s AI Action Plan

Today, the White House released "Winning the Race: America's AI Action Plan"—a comprehensive strategy to maintain America's advantage in AI development. We are encouraged by the plan’s focus on accelerating AI infrastructure and federal adoption, as well as strengthening safety testing and security coordination. Many of the plan’s recommendations reflect Anthropic’s response to the Office of Science and Technology Policy’s (OSTP) prior request for information. While the plan positions America for AI advancement, we believe strict export controls and AI development transparency standards remain crucial next steps for securing American AI leadership.
